Steve,
The fan I have is from
Quest Cooling 25530 Ave Stanford #211 Valencia, CA 91355 800-272-3267
It is their 14" pusher fan with their most powerful "Teminator" motor. Price was $110 plus tax, S&H, etc. it came to $129.63. This included a manual switch. They will sell you a thermostatic switch if you want it. The fan blades are straight and without circumferential support. I don't remember what they claimed for flow volume, maybe 1000cfm. It does have a shroud that permits a seal against the radiator. I had to use some rubber to get mine to seal because I couldn't get the thing to lie completely flat against the radiator without bending or cutting some sheet metal.
I did a quick search on the Web and came up with lots of info on Mobil 1 and related subjects. Haven't found a reference to the "Mobil 1 fiasco" yet, but there does seem to be agreement that seals start to leak when you switch from regular to synthetics. Here is one example of the kind of thing you find when you search on "Mobil 1 synthetic oil".

I don't believe that Mobil 1 was ever "black". That was an oil with graphite additive that was sold by Atlantic Richfield many moons ago. Now what was the name of that stuff? Can't remember, but nobody is going to put black oil INTO an engine; that's the color when you need to take it out!! Doomed from the start, no matter how good it might have been. What were those marketing guys thinking!!
Hope you're having a nice day!
